Faulty disc perhaps? Failing HDD or DVD Drive? These 1334 1335 errors, are they installshield errors? When you go to run the game?

Not the disc. The game itself is fine,very playable, I just can't get the 1.2 patch to install no matter what. The specific files that cause the errors I'm getting vary as well. I've downloaded the patch from 4 different sites and still no success. I'm just frustrated at the fact that I've spent more time trying to get this patch to install than I have playing the game. I've done a fair amount of Googling about these errors and can't seem find a specific solution since the patch is fairly new. I'm not the only one having this problem, so I guess all I can do is wait a week or so.
